Question

How do you graph `f(x) = 2x -4` on a coordinate graph?

Answer 1

Refer Explanation section.

Explanation:

Given -

y = 2x - 4

It is a linear equation. It is a straight line curve.
We need two points to fix it.

At x = 0 ; y = 2(0) - 4
(0 , - 4) is one point

At y = 0; 2x - 4 = 0
x = `4/2` = 2
(2, 0) is another point

Plot these two points. Join them with the help of a straight line.
